VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No, 279,686, dated June 19,1883,

- Application filed September 23, 1882. (No model.)

To all whom it may concern Be it known that I, D. ARGERBRIGHT, a citizenof the United States, and a resident of Troy, I in the county of Miamiand State of Ohio,

have invented a new and valuable Improvement in Vehicle-Springs; and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, makinga part of this specification,and to the letters and figures of reference marked thereon. Figure l ofthe drawings is a representation of this invention in a verticalsection. Fig. 2 is a perspective view of the S-shaped spring. Fig. 3 isa perspective view of the secondary spring. Fig. 4 shows a modificationof the spring shown in" Fig. 2.

This invention has relation to ,sulkies or road-carts; and it consistsin the construction and novel arrangement of parts, as will behereinafter fully described and claimed.

- In the accompanying drawings, the letter A designates the axle of aroad-cart or twowheel vehicle, and B laterally-arranged supports firmlysecured to said axle and extending upward to receive the lower branches,a, of the bent or S-shaped springs O, which are rigidlysecured to saidsupports by means of clips or other suitable fastenings in ordinary use.To the upper branches, b, of said S shaped springs the body orseat-frame D is fastened, said body or seat-frame having a dependingfootrest or support, E.

F indicates the shafts, which are firmly clipped to the axle, extendingforward horizontally therefrom, past the point of side entrance into thevehicle, and formed with an upward double bend, it, alongside the frontportion of the foot-rest, whence they extend forward, as shown in thedrawings.

' The dash G is attached to the foot-rest, and the front of thefoot-rest is connected to the shafts, or a cross-bar thereof, by meansof flexible or elastic couplings 0, which yield easily to the movementsof the foot-rest or seatframe. Usually these couplings are made incoil-spring form, and are carried around the cross-bar to which they arefastened.

H indicates side forms, which are designed to extend along the sides ofthe foot-rest and seat to present the appearance of a bodyframe. Thesesides are made detachable, so that they can be readily removed when notrequired.

being connected to the main spring by meansof adjustable clips orfastenings g, which can readily be loosened when necessary. Thesecondary springs L are adjustable toward or I from the bends d of themain spring 0. When it is desired to stiffen the main spring, in orderto support a greater weight, the secondary springs should be moved'outward from the bends d, according to requirement. \Vhen the secondarysprings are adjusted nearer to the bends c l, the spring will be moreyielding in character. In some constructions it may not be necessary tofasten the upper ends of the secondary springs to the main springs; butfor general use it is preferred to fasten both upper and lower ends ofthe secondary springs in order to prevent clicking or rattling.

A triple C-spring perforated to receive. a vertical rod or wireextending upwardly from a rubber cushion on that portion of the springwhich is secured to the axle has been provided with a holding-cap and anencircling-spring. The foot-rest has been connectedto the crossbar ofthe shafts prior to my invention, and I claim neither of theseconstructions,broadly, herein.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1. A bent or S-shaped vehicle-spring, 0, having adjustable secondarysprings, whereby the .main spring can be made more or less yielding,substantially as specified.

2. A road-cart consisting of wheels and axle, springsupports B, S-shaped main springs G and adjustable secondary springs L, seat D,depending foot-rest attached to said seat, flexible or elastic couplingsc, and shafts having the double bends it near the front portion of thefoot-rest, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
